Diff/Shafts etc - Drum vs Disc
Morning all,
Stumbled across a cheap XR4 rear end with diff, shafts and discs/calipers.
Is there much advantage or hassle by gong for this route?
I was happy with drums but this way I benefit from an LSD into the bargain.
Alternatively, can you fit drums to the bolt on shafts which come with the LSD?
Cheers
Rich

I believe the hubs are different for drums and disks and are interchangeable...
Is it an XR4x4 or XR4? only the 4x4 has an LSD
Opinions are like backsides..
Everyone has one, nobody wants to hear it and only other peoples stink!

Yeah go for it, has all the bits you need
Disks look far better behind alloys

I have an XR4x4 rear end. No problems. The hubs are the same on discs or drums. MNR do rear uprights to suit. Sierras with ABS have teeth cast
into the rear hub. These foul the upright and have to be turned off (for turned read angle grinder or file if no lathe available).
There's nothing wrong with rear discs and a recent thread here suggests that the weight penalty is only about a kilo if I remember correctly.

Ok thats good news.
I always thought they look better too, but wasnt sure if they were compatible.
Thanks

I've got the ABS 4x4 rear end, how much has to be take off to clear the hubs?

Bit of bad news, the XR4x4 (with leather interior, Konis etc) I was going to buy (for £250) has 4 knackered calipers which the guy says are not worth
rebuilding 
The MOT/Tax are up so that leaves the problem of moving it the 80 miles.
Considering it was mostly the back end I was wanting, thats a shame.
Is there much else that can be taken from a 4x4? I appreciate the front uprights are different but I assume the column etc is fine.
Did seem a bit too good to be true
Cheers

hi ritchie
the rack link is likely to be the wrong one as it will be power steering one which is cast, the column will be ok.
re the abs rings anyone who is building our cars we do this for you and will turn them down in the laith, it can of course be done by a grinder but
not as neat

Just a quick thought, if you put drums on the back just wait till you stand back and admire your car.........then you see those drums on display thro
your nice shiny wheels and you think my god they have got to go

Cheers marc et al
Im not going to bother with this one I dont think. 160 mile round trip and a load of grief if these calipers are indeed knackered (it failed the MOT
on those alone)
Im sure another one will come along but as Im in no rush I will hang out for the right one.
XR4x4 back end I think, bog standard everything else.

If its scrap, pay no more than £100. There isnt much of value on it - i sold loads of columns, switches, handbrakes, gearlevers etc for fivers and
tenners. Add in the time to break it, and its not such a good prospect. Leather makes it a bit better, but still bleak.

we do some plates that adapt the drums to disc brakes, as using the drum brake shafts saves some weight

I see. So in terms of weight saving, for a rear brake setup youre better off with brake shafts and then adapting them.
I just need to work out which shafts (bolt/slip in) go with which brakes/diff combo........and there was me thinking there werent many differences
between Sierra models 
What are your thoughts on 240 vs 260mm and Solid vs Plain for the fronts? I assume both types of caliper accept both sizes and i want the brakes to
be as good as they possibly can, but there seems to be a trade off with weight vs stopping power which i doubt needs to be that hairy on such a light
car.

hi rich
even with 240s on the brakes are pretty good ( and they are cheaper for the pads recon calipers etc )

Great cheers, Ill just see what comes along.
Was I right in thinking that both sizes & the vented and solid fit the calipers?

The vented discs are much wider than the solid (they are like 2 discs with a gap between them) you will need different calpipers for solid discs.

Many people suggest that the solid discs are plenty for a light weight car. Do you really think that you'll need the extra braking force? Is
the extra unspring weight a price worth paying? Remember that all up a sierra could weigh nearly 4 times a bike engined vortx and only the high
performance versions had the big front discs.

Yep, I agree, but if the donor you end up with has vented front discs, its a shame not to use them.

So Marc can I use the 3.38 diff that I will have with the shafts that I took out of my donor that had a 3.92 diff both push fit and fit the rear disk
brakes and callipers from a 4x4 using the brackets that you make to convert drums to discs.
If anyone can understand this can you advise.
